Anodic α-methoxylation and α-acetoxylation of substituted phenyl 2,2.2-trifluoroethyl sulfides and various fluoroalkyl phenyl sulfides were studied from both synthetic and mechanistic aspects. These anodicreactions were greatly affected by both substituent groups at the benzene ring and fluoroalkyl groups. Electron-donating substituents interfered with the reactions significantly.

从合成和机理两方面研究了取代的苯基2,2.2-三氟乙基硫化物和各种氟烷基苯基硫化物的阳极α-甲氧基化和α-乙酰氧基化。这些阳极反应受到苯环上的取代基和氟代烷基的影响很大。给电子的取代基显着干扰反应。强大的吸电子全氟烷基(C n F n + 1:n = 1-3)显着促进了这些阳极取代,而二氟和单氟甲基的取代则少得多。

Anodic methoxylation and acetoxylation of 2,2,2-trifluoroethyl sulfides and the corresponding nonfluorinated sulfides were comparatively studied. It was found that a trifluoromethyl group remarkably promoted anodic substitution and methoxy and acetoxy groups were introduced adjacent to the trifluoromethyl group of the sulfides. Longer perfluoroalkyl groups also promoted these anodic substitutions. These products were shown to be highly useful building blocks for the synthesis of fluoro organic compounds.
